IMPROVEMENT IN OBGIN-Irons..

iiggzighnle refsmr tn 'it these @attrs- Imh making niet -nf the same.

To WHOII I TMAY CONCERNI Be it known-that I, JOSEPH LORENZ, of Cincinnati, Hamilton county, Ohio, hnve invented a-new and useful Improvement in Organ-Pipes; a'nd I hereby declnre the following to be a. full, clear, and ex a .ct description thereof,

'reference'being had to vthe accompanying drawings, Yn iekilg.pei-t of this specification. v vMy invention relates. to a. forni of pipe for .church-organs, which combines the adveuteges of economy of space and material witha. fullerv nndvmore resounding nte than Athe eustomary pipe;

Figure l-s perspectiveview of a voxltumana pipe embodying my improvement.

Figure 2 is e. side eleyatiom'wt at its upper portion by au axial setion..

A is ,the wind-tube, enclosing the customary reed, (not seen in drawing and surmounted by the pipe B, composed ,of two conic'rlfrnsta, joined ba'se to base, and b'eing open at tslower 'end to a'ord' the usual communication with the eed, 51ndv closed at top by u. dome-like apex, c, to the upper frnstum C, intead of the usual open summit. I

At the common base o'f the two frusta, where the pipe is widest, is an elliptical ventage, D, for the'sounihand' where a symphonic note is desired, an additional 'and much-smaller orifice, d, may be provided, half way between the ventageD and the summit of the'dome c.

YA vox-humena pipe lthus formed, while occupying but hlf the height of an ordinairy open-topped pipe of the same tone'und4 volume of sound, is also found to possess a. more sonoron's and' resonant note. l A I claim herein as new, and of my invention-L Y The voz-hum'ana organpipe AB C 'c D, formed as and for the. purpose set forth.

^ Intestimony of which invlentiom'I hereunto set my hand.
